Anima laughter

Animal laughs no joke says expert
Many animals may have their own forms of laughter, says a US researcher writing in the magazine Science. Professor Jaak Panksepp says that animals other than humans exhibit play sounds that resemble human laughs.
These include the panting sounds made by chimps and dogs when they play and chirping sounds observed in rats.
This suggests that the capacity for laughter may be a very ancient emotional response that predates the evolution of humankind, says Panksepp.

Research suggests the capacity for human laughter preceded the capacity for speech.
